distinct_network

Stored Procedure to get the distinct network of a node 4 levels out

Instructions

This project uses maven, to build a jar-file with the procedure in this project, simply package the project with maven:

mvn clean package

This will produce a jar-file,target/procedures-1.0-SNAPSHOT.jar, that can be deployed in the plugin directory of your Neo4j instance.

cp target/procedures-1.0-SNAPSHOT.jar neo4j-enterprise-3.1.0/plugins/.

If you don't have maven, you can look at the releases tab of this github repository and grab a pre-compiled jar.

Start Neo4j and log in.

Create sample users:

    WITH ['Jennifer','Michelle','Tanya','Julie','Christie','Sophie','Amanda','Khloe','Sarah','Kaylee'] AS names 
    FOREACH (r IN range(0,100000) | CREATE (:Customer {CustomerID:names[r % size(names)]+r}))

Connect those sample users:

    MATCH (u1:Customer),(u2:Customer)
    WITH u1,u2
    LIMIT 100000000
    WHERE rand() < 0.1
    CREATE (u1)-[:FRIEND_OF]->(u2);

Try the stored procedure:

    MATCH (c:Customer {CustomerID:'Jennifer0'}) CALL com.maxdemarzi.distinct_network(c) YIELD value RETURN value
